This dinosaur was seven times bigger than a T rex

The word big does not do justice to this newly discovered dinosaur that shook the Earth 77million years ago.

Standing two storeys high at the shoulder, it was almost as long as three double-decker buses parked end-to-end.

Its skeleton, found by fossil hunters in Patagonia, Argentina, is the most complete remains of a titanosaur recovered anywhere in the world.

And remarkably, the beast, called Dreadnoughtus schrani, was still growing when it died, say experts.

Seven times bigger than a T.rex, it would have been an ‘intimidating sight,’ said palaeontologist Kenneth Lacovara, of Drexel University, in Philadelphia, who found the herbivore’s fossil.

‘With a body the size of a house, the weight of a herd of elephants and a weaponised tail, it would have been impervious to attack and feared nothing.’

For that reason he has named the beast after dreadnought battleships, which revolutionised naval warfare in the 1900s – the schrani name is a tribute to the US entrepreneur, Adam Schran, who funded his US team’s research.

After finding 70 per cent of the beast’s key bones, Prof Lacovara added: ‘It is the best example we have of any of the most giant creatures to ever walk the planet.’
